Japan makes some of the world's best fireworks including record breaking giant sized shells like the Yonshakudama! We'll head to a prestigious fireworks factory in Akita to see how they're made. The process includes 1) Milling 2) Granulation 3) Loading 4) Pasting The secrets of the trade are passed down from one generation to the next, family businesses that have been producing fireworks since the Meiji era. The larger the firework shell, the longer it takes to grow the stars or black pellets needed. They start as ceramic balls the size of a sesame seed and grow day by day, taking a month or more to make a Shakudama 3cm star. The Shakudama is a 18.5kg / 19 lb beast that you'll see launched at festivals outside Tokyo and urban areas. They get larger than that! The ni-shakudama, san-shakudama and yon-shakudama will literally blow you away with it's 750m launch height and width. 00:00 Start 02:00 Giant Firework Sizes & Details 02:42 World's Largest Firework Shell, YONSHAKUDAMA 04:20 Fireworks Factory, How it's Made 08:48 Loading the Firework Shells 15:18 Setting up the Launch Site 19:47 Japanese Fireworks Culture & History 22:54 Fireworks Launch Event 27:05 Large Shell Fireworks Launch ★ Supported by the Japan HANABI Association 一般社団法人日本花火推進協力会 Thank you very much!
